I am using drush 5.8 on Mac OSX
drush sql-query returns nothing at all, can't see to get any response whatsoever if I run (as example) drush sql-query "show tables;" from sites/default
the only response I can get is if I run the command above from above/outside the site root - and that is the "No database to operate on." error..
could be a very handy feature of drush for me, but I'm clueless on how to make it work and `drush help sql-query` doesn't provide me with any clues as where to execute from...
TIA
